Functional Features

• Octal D-type transparent latch with 3-state outputs
• High-speed operation, suitable for high-frequency applications
• Low-power consumption, ideal for battery-powered devices
• Transparent latch allows data to be latched and output in real-time
• 3-state outputs provide flexibility in connecting multiple devices

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing - Low-power consumption prolongs battery life - 3-state outputs allow for easy interfacing with other devices - Compact TSSOP package saves board space

Disadvantages: - Limited voltage range (4.5V to 5.5V) - Not suitable for extreme temperature environments

Working Principles

The SN74ABT574AGQNR operates as an octal D-type transparent latch. When the clock pulse (CP) is active, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The latch remains transparent as long as the output enable (OE) signal is active. When OE is inactive, the outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74ABT574AGQNR can be used in various digital applications, including but not limited to: - Data storage and transfer systems - Address decoding circuits - Bus interface units - Register banks - Memory modules
